All of the material in this patent document is subject to copyright protection under the copyright laws of the United States and other countries. The copyright owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure, as it appears in official governmental records but, otherwise, all other copyright rights whatsoever are reserved.

BACKGROUND OF THE INVENTION

The present invention generally relates to methods and apparatus for user data entry and, in particular, to methods and apparatus for recording and documenting observed data and, in preferred embodiments, such methods and apparatus are used by healthcare professionals in the healthcare context for recording and documenting observed data regarding patients.

Further in this respect, a patient conventionally receives healthcare from multiple medical and paramedical healthcare professionals over time, including by way of example, and not limitation, physicians, nurses, nurse practitioners, nursing assistants, and physical therapists. The healthcare is generally provided through a series of observation-intervention interactions between each healthcare professional and the patient, and data regarding such interactions is observed and recorded by the healthcare professional in the patient's electronic healthcare record so as to provide a comprehensive record of the patient's health and the healthcare provided to the patient over time.

Such comprehensive recording and documenting of observed data by a healthcare professional has drawbacks to the extent that the time required to record and document such observed data detracts from the time that a healthcare professional otherwise could spend with patients. For example, a nurse's function is largely divided into two broad categories of activities, comprising: patient contact and professional interaction; and, charting and medical recordkeeping. Approximately half of the time spent by nurses is dedicated to just charting and medical recordkeeping. This is believed to be largely due to the sequential nature of these activities, insofar as the charting and recordkeeping usually occur after the patient contact and professional interaction.

It is believed that improvements can be realized in the provision of healthcare by performing such activities in parallel rather than in series. One or more embodiments of systems, methods and apparatus in accordance with one or more aspects and features of the present invention are believed to represent such improvements.

As should be understood, any embodiment may incorporate only one or a plurality of the above-disclosed aspects of the invention and may further incorporate only one or a plurality of the above-disclosed features. Moreover, many embodiments, such as adaptations, variations, modifications, and equivalent arrangements, will be implicitly disclosed by the embodiments described herein and fall within the scope of the present invention.

Accordingly, while the present invention is described herein in detail in relation to one or more embodiments, it is to be understood that this disclosure is illustrative and exemplary of the present invention, and is made merely for the purposes of providing a full and enabling disclosure of the present invention. The detailed disclosure herein of one or more embodiments is not intended, nor is to be construed, to limit the scope of patent protection afforded the present invention, which scope is to be defined by the claims and the equivalents thereof. It is not intended that the scope of patent protection afforded the present invention be defined by reading into any claim a limitation found herein that does not explicitly appear in the claim itself.

Thus, for example, any sequence(s) and/or temporal order of steps of various processes or methods that are described herein are illustrative and not restrictive. Accordingly, it should be understood that, although steps of various processes or methods may be shown and described as being in a sequence or temporal order, the steps of any such processes or methods are not limited to being carried out in any particular sequence or order, absent an indication otherwise. Indeed, the steps in such processes or methods generally may be carried out in various different sequences and orders while still falling within the scope of the present invention. Accordingly, it is intended that the scope of patent protection afforded the present invention is to be defined by the appended claims rather than the description set forth herein.

Additionally, it is important to note that each term used herein refers to that which the Ordinary Artisan would understand such term to mean based on the contextual use of such term herein. To the extent that the meaning of a term used herein—as understood by the Ordinary Artisan based on the contextual use of such term—differs in any way from any particular dictionary definition of such term, it is intended that the meaning of the term as understood by the Ordinary Artisan should prevail.

Regarding applicability of 35 U.S.C. §112, ¶6, no claim element is intended to be read in accordance with this statutory provision unless the explicit phrase “means for” or “step for” is actually used in such claim element, whereupon this statutory provision is intended to apply in the interpretation of such claim element.

Furthermore, it is important to note that, as used herein, “a” and “an” each generally denotes “at least one,” but does not exclude a plurality unless the contextual use dictates otherwise. Thus, reference to “a picnic basket having an apple” describes “a picnic basket having at least one apple” as well as “a picnic basket having apples.” In contrast, reference to “a picnic basket having a single apple” describes “a picnic basket having only one apple.”

When used herein to join a list of items, “or” denotes “at least one of the items,” but does not exclude a plurality of items of the list. Thus, reference to “a picnic basket having cheese or crackers” describes “a picnic basket having cheese without crackers”, “a picnic basket having crackers without cheese”, and “a picnic basket having both cheese and crackers.” Finally, when used herein to join a list of items, “and” denotes “all of the items of the list.” Thus, reference to “a picnic basket having cheese and crackers” describes “a picnic basket having cheese, wherein the picnic basket further has crackers,” as well as describes “a picnic basket having crackers, wherein the picnic basket further has cheese.”

Referring now to the drawings, one or more preferred embodiments of the present invention are next described. The following description of one or more preferred embodiments is merely exemplary in nature and is in no way intended to limit the invention, its implementations, or uses.

It will be appreciated that, in this respect, the arm-mounted electronic device constitutes a hand-operated wireless peripheral device of the head-mounted electronic device.

In addition to or apart from use of the arm-mounted electronic device, it is contemplated that the head-mounted electronic device can be used to directly receive user input without the arm-mounted electronic device. Such user input may be accomplished by voice; by inclusion of one or more touch-sensitive areas on the head-mounted electronic device itself, such as at one or more areas of the surface of housing 206 or housing 306; the inclusion of buttons or other controls for manual actuation; and any combination of the foregoing; however, the arm-mounted electronic device preferably is used during dialogue with a patient to facilitate more natural appearing interaction with the patient, as opposed to having to touch the head-mounted electronic device to provide user input.

Exemplary Use of Head-Mounted Electronic Device in Recording and Documenting Observed Data in Healthcare Context

It is believed that the head-mounted electronic device can be effectively and efficiently used in methods and systems for recording and documenting observed data in a healthcare context so as to achieve substantial cost and time savings over conventional methods and systems. It is believed that efficiency improvements will result from real time, simultaneous data collection and recording during the actual provision of healthcare service to a patient, thereby avoiding much of the charting and documenting that is conventionally done after a patient is seen. Within such context, data entered by the user during a patient encounter preferably is recorded in the patient's electronic healthcare record of a conventional EHR software system. The following is an example of such contemplated use of the head-mounted electronic device.

To begin, a person dons the head-mounted electronic device on his or her head and attaches the arm-mounted electronic device to his or her preferred arm. The person then performs a credential verification process to insure the person is authorized to enter data and, moreover, is authorized to enter the particular type of data to be entered. In this respect, the person preferably must go through an identification verification process in order for the person to be authorized to observe and document healthcare information regarding the patient. Preferably, two-factor authentication is used including combination of biological and/or non-biological identifications.

As an example of a non-biological authentication, the person wearing the head-mounted electronic device enters an identifier of an authorized person and a password associated with the authorized person. The password preferably is entered using the display of the head-mounted electronic device, which preferably enables a person to scroll through and select, using the arm-mounted electronic device, a series of letters, numbers, and symbols constituting the password. Preferably, voice is not used in providing a password for security purposes; furthermore, using the head-mounted electronic device in conjunction with the arm-mounted electronic device eliminates the risk of keystroke visualization by an observer.

As another example, authentication using biologic identification may include facial recognition using a mirror, hand recognition, or voice recognition, among others. Voice recognition, for instance, preferably starts with a unique system generated sentence, phrase or word that is displayed to the suspect person wearing the head-mounted electronic device for reciting. In this respect, the “system” preferably comprises one or more computers or servers with software configured to interact with and support the head-mounted electronic device as described herein, as well as interact with conventional software for maintaining, updating, and retrieving electronic healthcare records of patients. The system preferably includes wireless communication capabilities for real time, concurrent wireless communication with the head-mounted electronic device during use by the person.

Upon being presented with the system-generated sentence, phrase or word, the suspect person then reads the displayed sentence or phrase aloud, and the system analyzes the tone and speech pattern against known tone and speech patterns of the person purported to be wearing the head-mounted electronic device. Using a unique, system generated phrase or sentence for voice analysis adds security by eliminating universal commands that can be generated or replicated fraudulently. Once a person's identity is verified, all observed and documented data is credited to the person. Timestamps, including date and time, preferably also are associated with the observed and documented data.

Next the subject must be identified that will be the object of the observation and data gathering. In the healthcare example chosen, the subject is the patient. Preferably, two forms of identification are used to identify and authenticate the patient before any data is recorded or documented. Any combination of non-biological and/or biological identifiers can be used.

For example, a patient's wristband generally will include, among other things, a machine-readable bar code representing a patient ID. In this scenario, a patient's wristband can be scanned using the optical reader of the arm-mounted electronic device, with the data read therefrom being communicated to the head-mounted electronic device and then communicated to the system for identification. In response, a resulting identification of a patient then preferably is communicated back to the head-mounted electronic device for reference.

Facial recognition of the patient then can be used to authenticate the identification. In this regard, the camera of the head-mounted electronic device takes an image of the face of the patient and communicates the image to the system, and an identification is communicated back to the head-mounted electronic device for reference; the identification communicated back may comprise a name or patient identifier corresponding to a matching reference image, or an indication of whether the image sent corresponds to a reference image as identified by a first identification of the patient, such as the patient ID read from the patient wristband. A reference image—or other reference biological information—of the patient preferably is obtained during patient registration. Thus, in this example, the patient ID identifies the patient and the facial recognition process authenticates the identification of the patient. It is contemplated that facial or other anatomic identifying algorithms can be used.

After identification and authentication of the person using the head-mounted electronic device and identification and authentication of the patient, the healthcare service is rendered by the person to the patient. Preferably, the healthcare service provided is at least partially scripted insofar as notes to be taken, parameters to be monitored, frequency of monitoring, general assessment, and medication information to be documented are all specified in a predefined document in the system. For example, a document for an exemplary protocol for a peripheral nerve block, including single injection and continuous fusion, is schematically illustrated in FIG. 9. This information can be contained in a database or other form of data storage for ready access and use.

With respect to the exemplary protocol of FIG. 9, it will be appreciated that the “Anesthesiologist Procedure Note” contains a predefined template for use by an anesthesiologist when performing the procedure of the protocol wearing a head-mounted electronic device in accordance with one or more aspects and features of the present invention. When the template is used to create the note, certain patient healthcare data taken from the identified and authenticated patient's electronic healthcare record is prepopulated in the note, such as for example, the patient's name, age, and gender, which preferably is obtained from the patient during patient registration. This type of data is represented by the placeholders shown between the angle brackets in courier new font the template in FIG. 9.

Once populated, the information in the note is shown on the display of the head-mounted electronic device during the procedure. The person performing the procedure and wearing the head-mounted electronic device at least in some embodiments preferably reads aloud the text of the note while performing the procedure, thereby confirming the information in the note while concurrently performing the procedure. If at any time the process needs to be suspended; for example in order to respond to a question, this can be accomplished either verbally or manually. A unique, specific command not commonly used in the verbal text is employed for this purpose, and predefined manual user input received via either the arm-mounted electronic device or the head-mounted electronic acts as a device pause/resume button.

Of course, it will be appreciated that certain information will not be predefined and will be included in the note by the person providing the healthcare service. Placeholders are provided for insertion of this type of information into the note by the person providing the healthcare service while performing the service. These placeholders—or option points—are represented with “xxxx” and shown in bold and underline in the template of FIG. 9. The option points appear within the body of the text for selection choices, such as medication injected or infused, total volume injected, rate of infusion, complication, etc., and each option point will be cued and entered in real time.

Using the integrated microphone of the head-mounted electronic device, cueing of the option point for data entry preferably is prefaced by a predefined system keyword or keywords, such as for example “cue”, followed by the specific key word(s) representing the data being entered. Such predefined system keyword(s) aids the system in avoiding misinterpretation of the same word(s) used elsewhere in the protocol and/or in different context. For example, stating “cue pulse” will cue the system and the key word “pulse” will blink in the display, indicating that the system is ready to receive data representing the patient's pulse. The data will then be verbalized, for example by saying “eighty two”. A verbal pause of 3-5 seconds then preferably will close the data entry point and the parameter will stop blinking. The duration of the pause after data entry and until the entry point closes can be adjusted depending on a user's preference.

As another example, a person might say, “cue sedation scale”. The options for this parameter would then appear on the display of the head-mounted electronic device, and the person could then make a selection using a touch-sensitive input or verbal command. Accordingly, predefined options can be presented when appropriate from which a person can select the data to be entered, and where appropriate no predefined options are presented and/or data that is not predefined or part of a menu for selection can provided by the person.

It will further be appreciated that some symbols will be used as part of the displayed data and will be recognized verbally. For example, “cue blood pressure” will open the blood pressure data entry point. Example data entry then would be spoken as, “one twenty over eighty”. This entry would be represented as 120/80. This will be appreciated as an example of how the system preferably recognizes spoken symbols throughout the program in proper context based on commonly used nomenclature.

Preferably, if a voice command is not recognized, then an alert is given indicating to the user that the voice command was not recognized. Such alert may be visual, auditory, or both. An exemplary visual alert comprise a blinking light shown in the display of the head-mounted device. An exemplary audible alert comprises a specific sound earmarked for use when a voice command is not recognized.

Nonverbal cueing also can be provided. For example, it is contemplated that touching a touch-sensitive area of the arm-mounted electronic device or a touch-sensitive area of the head-mounted device can trigger cueing; and positioning of the head in a predefined manner, or sequence of movements of the head, while wearing the head-mounted electronic device, as detected using the integrated gyroscope, can trigger cueing. Additionally, it is contemplated that one's eye can be monitored by the head-mounted device such that looking in a direction relative to forward that is abnormal will trigger cueing, such as looking to the outside corner of one's eye socket, or looking toward one's nose. A sequence of such glances can similarly be used as a way to trigger nonverbal cueing by the wearer of the head-mounted device.

Preferably, when data is selected or otherwise entered, a timestamp is associated with the entered data. Furthermore, the identification of the person performing the manual data entry, as identified and authenticated, is recorded in association with the entered data. Such information can be used later for, among other things, auditing, performance metrics, research, discovery and evidence in litigation, and benchmarking. Additionally, when a progress note or other transcription or documentation is made, the category of the system user is recorded in addition to the identification of user and timestamp.

FIG. 10 illustrates a view by a person wearing a head-mounted electronic device while performing the procedure of the protocol of FIG. 9. As illustrated, the person reads the text while performing the procedure. In this example, the displayed text changes from italics to non-italics as the text is read, thereby prompting the person to read next the first italicized word seen. Furthermore, the head-mounted electronic device is configured to take still frame photographs and/or video as the procedure is performed and store the data as part of the patient's electronic healthcare record for later reference, if and when needed. Examples of such usage in the healthcare context include sequential photographs documenting wound healing or video by physical therapy documenting patient ability or progress. Such recordings can be taken automatically or upon command of the person wearing the head-mounted electronic device.

With continuing reference to FIG. 10, it will be appreciated that the display is located in the upper right-hand portion of the person's view and does not lie directly in the line-of-sight of the person; alternatively, the display could be located in the upper left-hand portion of the person's view. The display reflects that point of progress for the procedure being performed. Preferably, the user through a series of specific commands is able to advance or track back the displayed portion of the text of the note.

In some preferred embodiments, in which the text of the note is not read while performing the procedure, the option points are still cued and data entered by the person while performing the procedure. Furthermore, in the case of a sterile medical procedure, such as the one in the exemplary protocol describe above, verbal data entry is most likely preferred and the arm-mounted electronic device may not be used by the person providing the healthcare service.

It will be appreciated that the above example protocol is a specific protocol chosen by, for example, an ordering physician, and a number of healthcare professionals are involved in the protocol, namely, the anesthesiologist as well as one or more nurses, nursing assistants, and pharmacists. The portions of the protocol pertaining to each such person preferably are routed by the system to the appropriate persons and, through a head-mounted electronic device of each person, a single coherent electronic healthcare record is created in real time including all of the pertinent data observed and documented together with a consolidated, chronological ordering of the events that transpired.

For example, a timestamp corresponding to the start of the infusion preferably is recorded by the system, and used to trigger subsequent workflows. A pharmacist subsequently preferably receives notification on his or her head-mounted electronic device to prepare and deliver infusion to the patient's nurse at a predefined time before the next infusion is due. The notice is sent by the system based on the time the infusion was started, the rate of infusion, and the total volume of infusion, as recorded and documented in real time in the patient's electronic healthcare record. As an example, when 0.2% bupivacaine infusion was started at 14:10, with a total infusion volume of 250 mL and a rate of 10 mL/hr, then the system calculates that the infusion will last 25 hours, and notice is provided to the pharmacist 24 hours after the start of the infusion. In this case, notice to the pharmacist will be sent at 14:10 the following day.

The foregoing protocol is an example of one of many that can be created and implemented. Moreover, appropriate protocols preferably are selected and combined for a particular patient, such as upon admission to a hospital or upon diagnosis of a condition and implementation of a treatment plan. For example, where a patient is admitted for a total knee replacement, several protocols preferably are identified for carrying out by appropriate healthcare providers, including for example a general medical doctor, a surgeon, an anesthesiologist, nurses, nursing assistants, and a physical therapist. Furthermore, each healthcare provider will have a range of protocols to choose and apply as determined to be most appropriate for the individual patient based on the professional judgment of the provider. For example, the surgeon may choose a general surgical protocol, or an orthopedic protocol, or a more refined orthopedic protocol specifically for total knee replacement. The anesthesiologist may choose a continuous femoral nerve catheter protocol for post-operative pain control, similar to the exemplary protocol described herein with reference to FIG. 9. Protocols preferably are activated or deactivated in the system at any time by authorized persons in their professional judgments. The system further preferably coordinates tasks contained in each applied protocol so that tasks are not duplicated and redundancy is eliminated.

It will be appreciated that the data collected from each person by way of that person's head-mounted electronic device is integrated to create a coherent patient electronic healthcare record. For example, both the surgeon and anesthesiologist protocols may require nursing assistants to collect patient vital signs every three hours. The system recognizes this, eliminates redundancy, and gives a single command notification to a nursing assistant at the appropriate time for collecting the patient vitals. The system further accommodates unique task commands in addition to predefined protocols and tasks therein. For example, a physician can add an order not found in the protocol. In this respect, the physician adds the task, specifies the parameters, and identifies the category of user to carry out the task. For example, a physician may add zolpidem 10 mg to be taken by mouth at bedtime as needed for insomnia, specifying the user category as nursing. The system would thereafter alert nursing at the appropriate time of the physician's order, preferably incorporating the order and due time in the listing of patients for a responsible nurse.

User-friendly features preferably form part of each protocol design. For example, a person using a head-mounted electronic device preferably is able to view, with a simple verbal command, a list of all parameters for which data is to be entered by that person during a protocol, such as “cue main menu”, whereupon the list of such parameters appears. Preferably, the predefined system keyword(s) for cueing a particular parameter are shown in the list, preferably in bold, whereby the person may cue a selected parameter for entry of the data for the selected parameter. Furthermore, currently due parameters preferably are visually differentiated from parameters not currently due. For example, parameters currently due may appear in red and those parameters not currently due may appear in black or another color, and time urgency may be visually displayed by a slow blinking text, such as when a parameter has not been addressed thirty minutes or longer after its due time.

In another example of a user-friendly feature, definitions used in the system preferably are easily referenced with a simple voice command. For example, a person might say “cue definition sedation scale”, the result for which appears on the display 202 of the head-mounted electronic device 200. A resulting display as might be seen is shown in FIG. 8.

It is also preferred that, in at least some embodiments, a person has the option to bypass or otherwise not use the template for a procedure and, instead, enter free text.

The head-mounted electronic device also preferably is used in physician case management. In this example, a physician is able to view a list of all patients under his or her care by saying, for example, “cue my patients”, whereupon a list of patients assigned to the physician is shown on the display of the head-mounted electronic device. The listing preferably identifies each patient name and current location. Furthermore, patients with currently due parameters or issues to be addressed preferably are visually differentiated from other patients, such as for example by displaying such patients in a different color or different manner. Visual differentiation can be accomplished through color differences and/or slow blinking indicating chronology or priority.

Embodiments in accordance with one or more aspects and features of the present invention also preferably enable and provide additional functionality, including: Internet connectivity for searching and retrieval of reference information for queries to things such as medical information or to better answer patient questions; translations utilizing language translation software that recognizes a spoken language and plays back or displays the translation; and identification and warning of adverse drug interactions prior to dispensing medications.

Still further, it is contemplated that the data entered by the person may be automatically supplemented with data acquired by sensors and machines. For example, such sensors and machines preferably interface with the head-mounted electronic device for electronically communicating information to the head-mounted device, which information then is included with the data entered by the user into the electronic healthcare records of the patients. In a more general sense, such electronic data collectors preferably interface with the head-mounted electronic device and system so as to add to and make more complete the user-entered data in the patient's electronic healthcare record. Data also can be supplemented from other software systems that interface with the head-mounted device, including for example conventional medication management systems such as Pyxis and Omnicell systems.

When a person is done using the head-mounted electronic device, the device is removed and placed upside down on a surface. The act of removing and inverting the device preferably locks the device from further use until a person is authenticated once again for use of the device. Locking of the device through removal and inversion preferably is detected by the integrated gyroscope within the device. Preferably, all persons authorized to use the device will be trained to remove and store the device in an inverted position when not in use.

In at least some embodiments, a camera of a head-mounted device is used to stream, either directly or indirectly, a line-of-sight view as seen by the wearer to a separate display device, such as a monitor. The streaming may be direct or may be indirect, such as through one or more routers, servers, the Internet, an intranet, or combination thereof. The user interface of the head-mounted device also is communicated from the head-mounted device to the separate display device. A person viewing the separate display device thereby is able to see a complete view of what the wearer of the head-mounted device sees, including the line-of-sight view of the wearer combined with a view of the user display of the head-mounted device. Indeed, FIG. 10 is representative of that which preferably would be displayed on the separate display device. It is believed that such an arrangement would be beneficial for example during training in use of the head-mounted device. The view streamed from the camera, the view of the user display, or both, further can be recorded for later viewing on a separate display device. Such recording can be used for training or tutorials. Such recording, if pertaining to an encounter with a patient, further can be stored in connection with the electronic healthcare record of the patient as part of the documentation or notes associated with the encounter.

In view of the foregoing, it will be appreciated that a person using one or more embodiments in accordance with one or more aspects and features of the present invention is able to perform and interact in his or her work environment as normal while seamlessly interfacing with a data entry system. Use of one or more embodiments of the present invention introduces additional knowledge, enhances interaction, and provides an enriched data record, as well as improves security, accuracy and timeliness in data observation and documentation. Furthermore, all functions can be tracked by user and chronology thereby providing increased accountability, and quality assurance measures can be followed by user specific reports detailing tasks not performed or not performed within an acceptable time frame. Indeed, the following advantages and benefits are provided by one or more embodiments in accordance with one or more aspects and features of the present invention, including but not limited to: quick data retrieval, reference information, language translations, construction and/or updating of an integrated patient electronic healthcare record in real time from multiple users, verification of qualifications for users, and positive identification of the subject from which data is observed and collected.

It will further be appreciated that one or more embodiments in accordance with one or more aspects and features of the present invention improve efficiency and accuracy in receiving and recording data in a patient's electronic healthcare record which data is observed during a patient encounter, thereby representing a technological solution to current inaccuracies and inefficiencies.
